Exact-match server upgrade

This NEMIX RAM kit delivers 512 GB across four 128 GB DDR5 RDIMMs rated at 6400 MT/s with CL52 latency and 1.1 V operation. Registered ECC architecture with 2Rx4 organisation ensures full-capacity recognition and error correction for the GIGABYTE MZ73-LM1 motherboard.

Verify motherboard population rules

Consult the GIGABYTE MZ73-LM1 manual for supported capacities, approved DIMM population order, and installation steps before ordering. The board requires 288-pin registered RDIMMs; UDIMM or SODIMM modules will not fit or function.

Registered ECC changes stability profile

Buffered registered design offloads the memory controller so every slot runs fully populated at rated speed. On-the-fly single-bit error correction prevents silent data corruption and unplanned reboots in production workloads.
